Product Sense: Designing a Payments Product Aimed at Italian Teenage Boys
Company: Google
Role: Product Manager
Category: Product Design & Strategy
Difficulty: medium
Interview Round: Other
As a PM, you are asked to build a payment product whose target users are teenage boys living in Italy. Describe who it serves, what it does, and how you would tell whether it is working.
```hint Who has to say yes?
A teenager rarely opens and funds a payment account alone. Think about who else must agree before the product exists in a family, and what each party needs before trusting it.
```
### Clarifying Questions
- Does "payment system" mean something teens use to pay (a card, a phone wallet or an app), or tooling for merchants who sell to teens?
- Which ages count as teenage here, and should the product carry a user through turning 18?
- Am I building this as Google, on top of an existing wallet and family-account setup, or as a new standalone company?
- Is the focus on boys a fixed constraint, or the launch segment for a product that can later serve every teenager?
### What a Strong Answer Covers
- The parties involved (the teen, the parent or guardian who funds and approves, merchants) and a reasoned choice of one teen segment to start with
- Pain points grounded in how teenage boys in Italy actually spend, such as gaming, sport, food with friends and transport, and in local habits such as cash use
- A concrete product with a prioritized first version, including parental controls that do not feel like surveillance to the teen
- Constraints specific to minors: identity checks, parental consent, blocking age-restricted purchases such as betting, and protection from scams
- A north-star metric with guardrails for safety and parent trust
### Follow-up Questions
- How should the product change for a 17-year-old who is about to become an adult?
- A parent wants to see every transaction and the teen wants privacy. How do you settle it?
- Would you grow through parents, schools or the teens' own friend groups, and why?
Overview: A product sense case asking a PM candidate to design a payments product for teenage boys in Italy. It tests segmenting teens and the parents who fund them, understanding how young people spend, designing parental controls, handling rules for minors, and choosing metrics that balance growth with trust and safety.
